Arguing with each other on social media - Besides being nonconstructive, it loops your friends, family and coworkers into your relationship issues and only adds increased pressure on them when they ask you about them later.

Criticizing your significant other on social media – Anything you want to say to your significant other should be said to their face – and only to their face. Besides, you'll never win their friends and family over by putting their loved one on blast on Facebook.

Guilting your significant other into using a couples shot for their profile photo – If your significant other uses their social media account for professional networking, they may want their profile pic to focus on them as an individual. Even if that's not their excuse, it's still OK for them to want their main identifying photo to be an image of themselves.

Cropping your significant other out of your profile photo – It's OK if you don't want to use that couple's photo as your main image, but don't twist the knife by using the photo anyway but cropping them out. And they won't appreciate the jokes they get about it from your mutual friends.

Posting racy pics/links of other people – If you wouldn't ogle another person in front of your significant other in public, why would you do it on social media where all of their friends and family can see you do it. Leave the "share" button on that new racy pic of Kim K. bootyalone.

Not accepting friend requests from significant other’s close friends and family – If you don't like their posts, just ignore or hide them. but ignoring them altogether opens your significant other up to a potentially awkward family conversation.

Posting embarrassing pictures of their significant other – Even if you wouldn't care if they did it to you, posting an embarrassing pic could leave them open to ridicule by friends, family and coworkers.

Having a joint Facebook account so you can keep tabs on each other – Just because you're a couple doesn't mean you're not two separate people. If you can't trust your significant other to have their own Facebook or Twitter account, you need to address the trust issue rather than force them to live under social media surveillance.

Conversing with exes, still being friends with them, or “liking” their content can be a big problem. ~ There is a reason your ex is your ex, and your current is current. A good rule is, if you wouldn't have the same interaction with your ex in front of your current significant other, then you shouldn't do it online.

Keep old photos of your ex in your photo albums – It's the social media equivalent of keeping them on your refrigerator, so you better have a compelling case against deletion.

Letting Facebook be the place they find out about your crazy views – Social media is a bad place to spring surprising views or personality quirks on your significant other. If you feel strongly enough about something to share it with everyone on the internet, you should feel comfortable sharing it with your partner.

Breaking big news on social media – Your significant other deserves to be the first person to hear about the new job or the big move. Don't share it with the world until you've shared it with them.
